Document Summary
2nf3: basic and clinical neuroscience imaging the brain. Electrical recording: detect changes in the electrical activity of the neurons, 2. Induce changes in the electrical activity of the neurons: 3. Structural imaging: sensitive to the density of different parts of the brain, 4. Dynamic imaging: records and manipulates ongoing changes in brain activity - electrical activity of cells, biochemical events, differences in glucose composition, blood flow, these i(cid:373)agi(cid:374)g te(cid:272)h(cid:374)i(cid:395)ues can do st(cid:396)u(cid:272)tu(cid:396)al i(cid:373)agi(cid:374)g as (cid:449)ell. Amplitude: frequency = number/unit in time, amplitude = height, eeg patterns are associated with particular behavioral states, beta rhythm, alert awake state, b. alpha waves, calm and resting, c. theta waves, drowsiness, d. e. delta waves, deep sleep. Eeg can be used to diagnosis epilepsy (multiple seizures) Shows greater activity in certain parts of the brain. Brief loss of consciousness: grand mal, convulsions of the body, falling down, and loss of consciousness. Eeg is used to provide information about cause and location of problems.
